In this paper, we present small and large signal data of a switched LNA hybrid circuit implemented using a low-loss and high linearity RF MEMS switching network on a GaAs MMIC wafer. The GaAs MEMS based reconfigurable LNA front-end circuit can achieve a 30 dB difference in in-band gain and attenuation (when the switch is turned on and off) while also being able to maintain a high gain (low noise figure) and P1dB compression point in comparison with the standard LNA MMIC used here.
